You did not specify if this is a standard desktop or a compact desktop. The difference is crucial. Compact desktops can usually only fit a compact USB card. Compact USB cards have only 2 ports not 4. This is due to space restriction. Very few manufacturers specify which card faceplate they supply with the cards. Very few manufacturers specify whether the cards fit compact or full size computer cases. They expect the buyer to know before ordering.
If you do a more extensive search you will uncover a few manufacturers that supply their USB card with both compact and full size faceplates. They are interchangeable. However, they usually are only 2 ports. Once again due to space restrictions. Almost all computers sold recently are the compact desktop, not the older more familiar tower type desktops. Which means that only a really old computer can use those 4 port cards.

The photo in post #8 is exactly what I was referring to. I assume both faceplates come with the unit. In that case, you are good to go. Unfortunately many manufacturers don’t supply both faceplates and don’t specify which will fit where.

You might want to consider backing up your existing drivers before installing the card. You might also want a driver backup after installing.
Good luck
